25 Claims. or. 70-68) This invention relates to slide fasteners, and particularly, to an improved combination lock slider therefor for preventing pilfering or unauthorized opening of bags and the like equipped with slide fasteners.

Various types of locking means have been suggested and used for locking the slider of slidefasteners against unintentional movement along the fastener stringers. Some of these locking means employed a key for actuating the locking mechanism. While such locks operated satisfactorily, oftentimes the key would become lost or misplaced, thereby preventing immediate opening of the fastener which was troublesome, as well as inconvenient. Also, in other locks heretofore suggested and used, the locking mechanism was attached to the bag or article and the slider carried a pivoted hasp or similar means for engaging the lock. In such arrangement this usually provided a flexible connection between the actual lock mechanism and the slider, which afforded an opportunity for slipping the fastener stringers through the slider and thereby permitting unauthorized opening of the fastener.

According to the present invention, there is provided a combination lock mechanism which is secured directly to the slider body so that the slider is locked directly to the fastener stringers and elements inside the slider channel there eliminating the above mentioned disadvantages.

It is the general object of the present invention to provide an improved combination lock for sliders of slide fasteners which consists of a minimum number of parts and which may be easily and conveniently applied to the fastener.

It is another object of the inventor to provide an improved combination lock slider which is simple and inexpensive in its constructionand yet at the same time efficient and eifective in its use.

It is a further object of the inventor to provide an improved combination lock slider for slide fasteners which is neat in appearance, and strong and rugged in its construction. 7

Various other objects and advantages of this invention will be more apparent in the course of the following specification, and will be particularly pointed out in the appended claims.

Fig. 18 is a sectional view taken on line 1818 of Fig. 15; and

Fig. 19 is a perspective view of the locking member of this latter modified construction.

Referring more particularly to the drawings, the improved combination lock slider of the present invention shown incorporated with a conventional type slide fastener which comprises a pair of flexible stringers 2 hav- "'.g a series of spaced-apart interlocking fastener elements c arranged along the adjacent edges thereof which are engaged and disengaged by longitudinal movement of the slider therealong in a well-known manner.

in accordance with the present invention, the embodiment shown in Figs. 1 through 5 of the drawings, comprises a body member 4 which is preferably die-cast, havin spaced-apart wing portions 5' and t3 integrally connected together at one end by a neck portion 7 so as to provide substantially a Y-shaped channel 8 therebe.

tween. On the outer side of one wing portion or face of the slider body 4 there is positioned, in a housing portion 9 carried thereby, the improved combination lock mechanism of my invention. Such lock mechanism con sists of a pair of horizontally disposed dials or rotatable operating members 16 and 12. which are positioned in recesses i3 and 14, respectively, in the opposite sides of the housing portion 9 and are rotatably mounted on pins 15 and 16, respectively, carried by the housing. As shown in Fig. 6, each of the rotatable members it) and 12 consists of two interengaging disk-like parts 17 and 18 constructed and arranged so as to be spaced apart around the periphery thereof whereby a box cam raceway or maze 18a and 19, respectively, is provided therebetween. The side walls of each of these raceways 18a and 19 have a plurality of spaced-apart cam-like portions 29 and corresponding recesses 21 arranged therearound, and one enlarged cam portion 22 in the bottom part 38 and a corresponding enlarged recess 23 in the upper part 17 for a purpose hereinafter to be described.

On the outer face of each of the upper parts 17, there is arranged therearound adjacent the periphery thereof calibrations or markings, such as numerals or letters, or other suitable markings 24 which are adapted to register with apertures or windows 25 and 26, arranged in the outer face 27 of the housing. The outer periphery of each of these upper parts 17 is preferably knurled as at 28, which knurled edge portions extend outwardly beyond the respective side edges of the housing and by means of which the rotatable members are adapted to be rotated manually.

Directly opposite each of the rotatable members it and v a 12, there is arranged tumbler-dike locking members 2) and 30, respectively, which are disposed for reciprocable movement in openings 31 and 32, respectively,arranged in the upper wing portion 5 of the slider body and which Communicate with the channel 8 therein. These locking members 29 and 30 have locking projections 29:: and-36a,

respectively, on one end thereof and outwardly extending lug-like portions or followers 2% and Stlb, respectively, on the opposite end, as more clearly shown in Fig. 7. These lug portions 295 and Sill; are disposed in the respective raceways 18a and 19 of therespeciive rota members 16 and 12, as more clearly shown in i .gs. s and 5 of the drawings. On the outer side of the wing portion 8 there is provided preferably a lug portion 33 to which a pull member 34 is movably attached for manipulating the slider in opening and closing the same.

Having described the construction of this embodiment ofmy invention, its operation will now be described. it will be understood that cam portions 22 and the recesses 23 cause the rise and fall of the locking members 29 and 30 when the rotatable members it? and 2 re rotated so that the proper combination to open the lock cannot be easily felt by trial and error when these members are rotated when the combination is not known to the operator. Also, it will be understood that the enlarged cam portions 22 and the corresponding recesses. 33in the respective raceways 18a and 19 are positioned with respect to a predetermined selected calibration or marking 24 on the respective rotatable members so that the locking members 29 and 30 will be moved to their unlocked positions only when such calibration or marking appears in the respective apertures or windows 25 and of the respective rotatable members. It will be assumed that the locking members 29 and 30 are in their locked positions with the respective locking projections 29a and 36a carried thereby projecting into the slider channel, as shown in Fig. 4, when it is desired to open the lock. The operating members it and 12 are rotated and in so doing, it will be seen that the respective lug portions 2% and 3012 will follow the respective raceways 18a and 3.9. When the respective predetermined selected calibrations or markings for opening the lock are positioned opposite the respective windows or apertures 25 and 26, the respective locking members 29 and 30 will be moved outwardly due to the action of the respective enlarged cam portions 22 and recesses 23. By such movement, it will be seen that the respective locking projections 29a and 34):: thereof are moved out of the slider channel 8 and out of engag ment with the interlocking elements 3 therein, as shown in Fig. 5, thereby permitting the slider to be moved along the stringers. When it is desired to lock the slider against movement the rotatable members It and 12 are rotatably positioned so that the proper opening combination, i. e., markings 24, are moved out of register with the windows 25 and 26. Upon such rotatable movement, it will be seen that the respective locking members 29 and 36 are caused to be moved inwardly into the channel 3 and again into engagement with the fastener elements 3. It will be understood that the raceways 18a and 19 are constructed and arranged so that the locking projections 29a and 35in extend into the channel 8 of the slider into engagement with the fastener elements therein in all rotatable positions of the rotatable members it and 12 except when the rotatable members are positioned at the predetermined selected rotatable position or combination at which point they are moved and held out of the channel 3 by the enlarged cam portions 22 in the raceways.

In Figs. 8 through 13 there is shown a modified lock slider construction of my invention. in this embodiment, as before, there is provided a body member 46, also preferably die-cast, having spaced-apart wing portions 41 and 42 integrally connected together at one end by a neck portion 43 so as to provide substantially a i -shaped channel 44 therebetween. On the outer side of one of the wing portions or face of this body member, there is provided a housing portion dlla, in which there is mounted a pair of dials or rotatable operating members 45 and 46. These operating members 45 and 46 are rotatably mounted in parallel relation on a pin member 47 and are spaced apart from one another by an arcuate portion 48 carried by the housing.

As more clearly shown in Figs. 11 and 12, on the inner side of the rotatable members 45 and 46, there is arranged box cam raceways 4i and 56, respectively, having spaced-apart cam-like portions 521 and 52, respectively, arranged around the side walls thereof. There is also provided in these raceways 49 and 56 an enlarged cam portion 55 and a corresponding enlarged recess 56 respective rotatable members 45 and 46, in the housing a, there is arranged preferably spring-like members 63 and 64, respectively, which cooperate with the respective knurled edge portions 59 and 6b of the rotatable members, which spring members are adapted to aid in positioning and holding the respective operating members and 46 in their rotatable adjusted positions.

Directly opposite each of the rotatable members 45 and 46, there is arranged in an aperture 65 extending through the upper Wing 41 of the slider body 4il centrally thereof and communicating with the channel 44 therein, a pair of tumbler-like locking members 66 and 67 which are adapted to be moved reciprocably into and out of the slider channel. On one end of each of these locking members, there is arranged locking projections 68 and 69, respectively, and on the opposite end thereof outwardly extending lug-like portions 70 and 71, respectively, as more clearly shown in Fig. 13. These lug portions are disposed in the respective raceways 49 and of the rotatable members 45 and 46, as more clearly shown in Figs. 11 and 12 of the drawings. 7

This embodiment of my invention functions in the following manner. As in the embodiment previously described, it will be understood that cam portions 51 and 52 of the raceways 49and 50 cause the rise and fall of the locking members 66 and 67 when the operating members 45 and-46 are rotated so that the proper combination to open the lock cannot easily be felt by trial and error when these members are rotated and the proper combination is not known to the operator. Also, it will be understood, as before, that the enlarged cam portions are positioned with respect to a predetermined selected calibration or marking on the respective rotatable members 45 and 46 so that the locking members will be moved to their unlocked positions only when such calibration or marking is disposed opposite and registers with a hair line mark 72 arranged centrally of the arcuate portion 43 of the housing, as shown in Fig. 8.

It will be assumed that the locking members 66 and 67 are in their locked positions with the respective locking projections 68 and 69, thereof, extending into the slider channel and into engagement with the fastener elements 3 therein, as shown in Fig. 10. When it is desired to open the lock in order to move the slider along the fastener elements, the operating members 45 and 46 are rotated until the respective predetermined selected calibration or markings on the periphery of the rotatable members 45 and 46 are positioned in line with one another opposite the hair line marking 72. Insuch position of these rotatable members, it will; be seen that locking'members 66 and 67 are moved outwardly with the respective: locking projections 68 and 69 carried thereby moving out of the slider channel 44 and out of engagement with the fastener elements 3 therein, thereby permitting the slider to be moved along the fastener to open and close the same. When it is desired to lock the slider against movement, the operating members 45 and 46 are again rotated so as to move the predetermined rotatable calibration or markings out of register with the hair line mark 72 whereby the locking members 66 and 67 are moved inwardly due to the construction and arrangement of the cam portions 51 and 52 so that the respective locking projections 68 and 6? again project into the slider channel in engagement with the fastener elements 3 therein.

In Figs. 14 through 19 there is shown another modification of the lock slider of my invention which is similar to the embodiment just described. in this embodiment, as before, there is provided a body member 89 also preferably die-cast, having spaced-apart wing portions 81 and 82 integrally connected together at one end by a neck portion 83 so as to provide substantially a Y-shaped channel 84 therebetween. On the outer side of one of the wing portions or face of this body member, there is proided a housing portion 86a, in which there is mounted a pair of dials or rotatable operating members 85 and 86.

These operating members 85 an 86 are rotatably mounted in parallel relation on a pin member 87 and are spaced apart from one another by an arcuate portion 88 carried by the housing.

On the inner side of each of the rotatable members 35' and 86, there is arranged box cam raceways 39 and 99, respectively, having spaced-apart cam-like portions 93. and 92, respectively, arranged around the side walls thereof. There is also provided in these raceways 39 and 99 an enlarged cam portion 95 and a corresponding enlarged recess 96 for a purpose hereinafter to be described.

Around the periphery of each of the rotatable members 85 and 06, there is arranged as at $7 and 93, respectively, calibrations or markings, such as numerals or letters. On the outer edge portion of each of these rotatable members,

there is arran ed around the eriher thereof, knurled or notched portions 99 and ran, respectively, for manual rotation of these members. in recesses lll and 192, respectively, positioned below the respective rotatable members 85 and 36, in the housing Si o, there is arranged preferably spring-like members 1 93 and 184 respectively, which co-operate with the respective knurled edge portions 5? and 195 of the rotatable members, which spring members are adapted to aid in positioning and holding the respective members and 36 in their rotatable adjuster positions.

Directly opposite each of the rotatable members 35 and 86, there is arranged in an aperture 135 extending through the upper wing 81 of the slider body 3% centrally thereof and communicating with the channel therein, a pair of tumbler-like locking members and ill? which are adapted to be moved reciprocably into and out of the slider channel. On one end of each of these looking members, there is arranged locking projections its and 199, respectively, and on the opposite end thereof outwardly extending lug-like portions 119 and E11, respectively, as more clearly shown in Fig. 19. These lug portions are disposed in the respective raceways 39 and 9d of the rotatable members 85 and 8 5, as more clearly shown in Fi s. 16 and 17 of the drawings.

At each end of the housing portion ell r there is arranged preferably yone-shape portions 112 and to which are attached pull members 114 and 115, respective ly, for moving the slider along the fastener stringers to open and close the fastener in a well known manner. The locking mechanism of this latter embodiment of my invention functions in the same manner as the embodimerit previously described.

As a result of my invention, it will be seen that ther is provided a combination lock which can be easily incorporated with the sliders of slide fasteners. It will be seen that the slider cannot be manipulated to open or close the fastener unless the proper locl: opening combination is known to the operator thereby eliminating the danger of unauthorized opening of the bag or articleoth r forms may be devised within the scope of my in-' vention as defined in the appended claims.
